I want to fit a new towel rail in place of radiator in bathroom. I have a Combi Boiler system.
I have closed off both valves on radiator, drained the radiator and removed radiator from wall. With the radiator off I opened both valves to check that water was coming out but no water came out of either. Is this normal with a Combi boiler and how do I get the water to come back when I have fitted the towel rail. Thanks
